Abstract

By combining advanced device modeling with computational physics, microscopic changes in quantum many-body interactions of quantum dots are described as a function of macroscopic device parameters without a priori assumption on the confining potential. In planar coupled quantum dot structures, spin control can be achieved by modulating exchange interaction with an external gate as in conventional field effect transistors. These new features, coupled with recent advances in quantum dot physics constitute the basic ingredients for a solid state technology for quantum information processing.
